GAS-PRODUCER.

Specification of Letters Patent.

Patented Jan. 2, 1906.

1'0 (tit whom it may concern.-

Be it known that we, ()RVILLE O. SKINNER and J AMns E. SHEAFFER,citizens of the United States, residing at Burnham, Pennsylvania, haveinvented certain Improvements in Gas- Producers, of which the followingis a specification.

The object of our invention is to provide means for preventing theformation of clinker on the walls of a gas-producer.

In a companion application filed of even date herewith by James E.Sheaffer the process of preventing clinker is claimed, and thisapplication is limited to the apparatus for carrying the process intoeffect.

In the accompanying drawings, Figure 1 represents, in vertical section,a well-known type of gas-producer illustrating our invention; and Fig. 2is an enlarged sectional view of part of Fig. 1.

In the drawings, 1 represents the cylindrical body of the producer; 2,the tapering ashhopper at the bottom of the same; 3, the watersealedash-pit; 4, the central air-pipe; 5, the air-distributing hood of thesame; 6, the gasoutlet, and 7 the valved feeders for the fuel. Theproducer has a central hollow vertical shaft 8, provided with projectinghollow arms 9, which extend into the fuel at or near the hot zone of thes'amethat is to say, between the bed of ashes in the ash-hopper and thegreen fuel in the upper portion of the producer--these arms having thepurpose of agi tating and stirring up the mass of fuel in the producer,so as to insure the proper flow of air therethrough and prevent theformation of clinker. Each of the arms 9 is watercooled, the Water beingconveyed thereto through a central pipe 10 in the hollow shaft 8, thispipe being provided with branches 11, one in each of the hollow arms 9,the water being delivered by these branches at the outer end of eachhollow arm and returning through the arms and hollow shaft to adischarge-pipe 12 above the top of the furnace. Instead of closing theends of the arms 9, as usual, however, we provide the same withperforated nozzles 13, from each of which a jet or stream of water willbe projected against the walls of the producer in the hot zone of thefurnace, the effect being that the incandescent material which wouldotherwise adhere to the 'walls and unite to form clinker is cooled andsoftened, so that it will readily pass down into the hopper 2 along withthe ashes, the walls of the fuel-chamber being thereby maintainedrelatively free from accumulations of clinker, so that the orderly andcontinuous operation of the furnace is not interfered with.

Having thus described our invention, we claim and desire to secure byLetters Patent-- 1. The combination in agas-producer, of a stirring-armmounted within the producer, the arm having a nozzle through which wateris projected into the mass of fuel at the point where clinker usuallyforms, substantially as described.

2. .The combination of a gas-producer with a water-supply pipe mountedwithin the producer, said pipe having a nozzle adjacent to the innerwall of the producer for projecting a jet or stream of water toward thesaid inner wall of the producer into the mass of fuel where the clinkerusually forms, substantially as described.

3. The combination of a gas-producer having a rotating shaft with hollowarms projecting into the mass of fuel in the producer, and means fordischarging jets or streams of water from said arms into the fuel,substantially as specified.

4. The combination of agas-producer having a rotating shaft with ahollow arm projecting into the mass of fuel in the producer. and meansfor discharging a jet or stream of water from the outer ends of said armagainst the walls of the producer, substantially as described.

5. The combination of a gas-producer having a hollow rotatingwater-cooled shaft, with projecting water-cooled arms thereon, andwater-discharging nozzles secured to the ends of said arms,substantially as specified.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
